Perhaps it may be thought strange that Carthage and Rome had not come into conflict before the time of which we are writing, for the distance between the island of Sicily and the African coast is so small that but a few hours would have been occupied in sailing across. It may be accounted for by the facts that the Carthaginians attended to their own business, and the Romans did not engage to any extent in maritime enterprises. On several occasions, however, Carthage had sent her compliments across to Rome, though Rome does not appear to have reciprocated them to any great degree; and four formal treaties between the cities are reported, B.C. 509, 348, 306, and 279. It is said that when Pyrrhus, King of Epirus, was about to leave Sicily, he exclaimed: "What a grand arena [Footnote: _Arena_ in Latin meant "sand," and as the central portions of the amphitheatres were strewn with sand to absorb the blood of the fighting gladiators and beasts, an arena came to mean, as at present, any open, public place for an exhibition. To the ancients, however, it brought to mind the desperate combats to which the thousands of spectators were wont to pay wrapt attention, and it was a much more vivid word than it now is.] this would be for Rome and Carthage to contend upon!" It did not require the wisdom of an oracle to suggest that such a contest would come at some time, for the rich island lay just between the two cities, apparently ready to be grasped by the more enterprising or the stronger. As Carthage saw the gradual extension of Roman authority over Southern Italy, she realized that erelong the strong arm would reach out too far in the direction of the African continent. She was, accordingly, on her guard, as she needed to be. At about the time of the beginning of the war with Pyrrhus, a band of soldiers from Campania, which had been brought to Sicily, took possession of the town of Messana, a place on the eastern end of the island not far from the celebrated rocks Scylla and Charybdis, opposite Rhegium. Calling themselves Mamertines, after Mars, one form of whose name was Mamers, these interlopers began to extend their power over the island. In their contests with Hiero, King of Syracuse, they found themselves in need of help. In the emergency there was a fatal division of counsel, one party wishing to call upon Rome and the other thinking best to ask Carthage, which already held the whole of the western half of the island and the northern coast, and had for centuries been aiming at complete possession of the remainder. Owing to this want of united purpose it came about that both cities were appealed to, and it very naturally happened that the fortress of the Mamertines was occupied by a garrison from Carthage before Rome was able to send its army.
